WARNING: Back up your Astrid 2 before doing the Astrid 3 upgrade! I just updated to Astrid 3.0 ("Update Available"). Silly me, I didn't read the notes other than to see that Astrid 3 was "all new". My tasks vaporized! The I tried to "restore" and it said I had to buy an add-on pack to do that. No indication of whether the restore in V3 is compatible with saved tasklists from V2. The experience left me cold. I uninstalled Astrid 3 and reverted to V2 via the link http://bit.ly/oldastrid. Then I restored from the saved list on my SD card from the scheduled backup that Astrid did last night. I still lost some tasks I entered today.
